Abstract (en)
There is provided a technique installing a memory on a developing cartridge and a drum cartridge, and capable of reducing an operation load for a user at the time of attachment of the drum cartridge to which the developing cartridge is attached to an image-forming apparatus. The drum cartridge includes a first memory 71 having a first electrical contact surface 711, and a first holder 72 holding the first electrical contact surface 711 such that the first electrical contact surface 711 is movable relative to a drum frame. The developing cartridge includes a second memory 81 having a second electrical contact surface 811, and a second holder 82 supporting the second electrical contact surface 811 such that the second electrical contact surface 811 is movable relative to a casing. A plate 200 connects the first holder 72 and the second holder 82 to each other in a state where the developing cartridge is attached to the drum frame. The second holder 82 moves together with the plate 200 in accordance with movement of the first holder 72. With this structure, an elastic member need not be provided in the second holder 82, thereby reducing an operation load for the user.
